1. Clean water. No pollution, no toxic, harmful or odorous substances, especially heavy metals and organic substances.
2. Weak alkaline water. The PH value is weakly alkaline (7.0 1-8.0) to maintain the acid-base balance.
3. nutritious water. It contains essential mineral elements for human body. The ions of this important element affect or determine the pH value, hardness and water mass of water.
4. Hard water keeps a certain hardness. Various ions in water constitute the hardness of water. Hard water contains high calcium. Hard water can prevent harmful components (such as lead, cadmium, chlorine and fluorine) from playing a harmful role. The distinction between hard water and soft water is generally based on the total hardness of 75mg/ 1 (calculated by calcium carbonate), which is between 30 and 200.
5. Water with moderate dissolved oxygen and carbon dioxide content (dissolved oxygen in water is not less than 7 mg per liter). Water rich in dissolved oxygen can metabolize and excrete acidic toxins in the body.
6. Small molecular water (half width of NMR is lower than 100Hz).
7. Living water, that is, water whose nutrition and physiological functions have not deteriorated, is alive. The functions of water include solubility, permeability, diffusion, metabolism, emulsification and cleaning.
In fact, whether water meets the standard of healthy water depends on whether the contents of minerals and trace elements in water meet or exceed international or national standards. Only those that meet or exceed the standard are healthy water worthy of long-term drinking, which can really help people's health.
